Using a reliable tire pressure gauge, ensure that each tire is inflated to the manufacturer’s recommended pressure, which can typically be found on a sticker located on the driver’s side door jamb. If any tire is under-inflated, inflate it to the correct pressure and observe whether the TPMS resets itself after a short drive. In many cases, the system will automatically recalibrate once the tire pressure is corrected.
If the tire pressures are all within the recommended range and the TPMS still does not work, the next step is to inspect the TPMS sensors. Each tire is equipped with a sensor that monitors the air pressure and transmits this information to the vehicle’s onboard computer. Over time, these sensors can become damaged or may fail due to battery depletion, as many TPMS sensors are powered by batteries that have a limited lifespan. To check the sensors, it may be necessary to use a TPMS tool, which can read the sensor data and determine if they are functioning correctly. If a sensor is found to be faulty, it will need to be replaced.
In addition to checking the sensors, it is also important to examine the vehicle’s wiring and connections related to the TPMS. Loose or corroded connections can disrupt the communication between the sensors and the vehicle’s computer, leading to a non-working system. Inspecting the wiring harness for any visible damage or disconnections can help identify potential issues. If any problems are found, repairing or replacing the affected components may restore functionality to the TPMS.
Another factor to consider is the vehicle’s onboard computer system. In some cases, a software glitch or error may prevent the TPMS from operating correctly. To address this, it may be beneficial to reset the TPMS using the vehicle’s onboard diagnostic system. This process typically involves using a scan tool to clear any error codes and reset the system. If the problem persists after a reset, it may be necessary to consult a professional mechanic or dealership for further diagnosis.
